Introduction of stepper motor:-
A stepper motor is a brushless dc motor and the stepper motor rotor rotates in discrete angular displacements when its stator windings are energized in a sequence programmed manner. stepper motor Rotation possible because of magnetic field interaction between rotor poles and stator poles of the sequentially energized field winding. The rotor doesn't consist of any electrical windings but has a rotor consist salient and magnetic/or magnetized poles.
The stepper motor is a digital actuator its input is in the form of digital signals and its output is in the form of discrete angular rotation. The angular rotation is dependent on the number of input pulses to the motor is suitable for controlling the position by controlling the number of input pulses. Thus they are identically suited for an open position and speed control.
